I've used Golfpride Tourwraps and Victory gips and I now use Lamkin Crossline.....the Crossline's are FAR more durable in my opinion that the Golfpride products.
I hit them with sandpaper once a month and really wash them good with a scrubber and dish washing soap. This really makes them tacky again.
I have used them for two seasons and I golf a good bit....they'd be good for another season but I am replacing them this year.
